The present invention relates to a receptacle. In particular, theinvention relates to a receptacle for the disposal of rubbish orsanitary waste.

BACKGROUND OF THE INVENTION

Many types of waste disposal receptacles are available, particularlyreceptacles that are designed for the disposal of women's sanitaryproducts. Such bins are not generally emptied on site, but are takenaway and replaced with a fresh bin, due to the hazardous nature of thewaste.

Sanitary bins are usually accessed via a flap which allows wastematerial to be placed into the receptacle. This requires that the userhandles the bin around the area of access to the bin to expose the flap.This can also accumulate waste material in an area around the access tothe receptacle which can be unsightly, and potentially a health hazard.

Other types of receptacles are also available for disposal of foodscraps and other such waste. Similar issues arise with these products aswith sanitary bins, as food and other waste material can build up aroundthe access area causing health issues for example.

It is an object of the invention to provide a receptacle which overcomesor at least reduces some of the disadvantages of presently availablereceptacles or which at least provides the public with the usefulalternative.

Other objects of the invention may become apparent from the followingdescription, which is given by way of example only.

DETAILED DESCRIPTION OF THE FIGURES

The invention, in broad terms, provides a receptacle for containingwaste material. The receptacle may be especially suitable for use inrest rooms for the disposal of sanitary waste. The receptacle may alsobe used for the disposal of other types of rubbish including food scrapsor other perishable wastes. The receptacle is adapted to be able toreceive waste material with a reduced amount of contact between the userand the access to the receptacle, and is also adapted to be removed as acomplete unit for later disposal of the waste material containedtherein.

A preferred embodiment of the invention is shown in FIGS. 1 and 2. Areceptacle 1 is made up of a body 20 and a lid 30.

The body 20 is defined by a base 21 and at least one side 22. The bodyas shown in these Figures is cylindrical in shape thus including onecontinuous side. The base 21 is convex in shape when viewed from theoutside of the receptacle 1. The body 20 has an open top 23 (best seenin FIG. 2).

The lid 30 is defined by at least one side 31 (again cylindrical asshown in the Figures) and a top 32. The lid has an open base 33 (bestseen in FIG. 2). The lid 30 includes an aperture 35 located in the side31. The lid side 31 is adapted to fit snugly within and adjacent thebody side 23 while allowing movement of the lid 30 relative to the body20 between an open and closed position. The interaction between the lid30 and the body 20 is telescopic in nature with the lid 30 beingreciprocally movable as a whole in relation to the body 20. The bodyside 22 and the lid side 31 lie adjacent each other in a manner thatallows telescopic movement (or reciprocal movement) of the lid 30relative to the body 20. FIGS. 1 and 2 shows the lid 30 in the openposition.

When the lid 30 is in the open position (as seen in FIGS. 1 and 2),waste material can be deposited into the receptacle 1 through aperture35. The waste material (not shown) is placed into the receptacle 1 viaaperture 35 and falls through the open base 33 of the lid 30 and intothe body 20 coming to rest at/or adjacent to the closed base 21 of thebody 20.

As the lid 30 is movable within body 20, any waste material that mayadhere or otherwise become attached around, or to, the aperture 35 isheld within the body 20. This is important from a visual and hygieneaspect. Visually, it is unattractive to see waste material on theoutside of the receptacle. Hygienically, the presence of such wastematerial is a problem as users could come into contact with that wastematerial, with consequent health risks. If the lid 30 plus aperture 35was held outside body 20, then the unattractive visual and unhygienicaspects can readily occur.

The lid 30 includes a handle 34 at its apex. This handle 34 assists theuser to move the lid 30 to an open position from a closed position. Aswill be readily apparent, the handle 34 may be substituted by a varietyof types of opening means which extend from the lid, such as loops,toggles or other such means. Preferably the handle 34 (or other forms ofopening means) will be positioned away from the aperture 35 to minimisecontact with the aperture by the operator when exposing the aperture 35.This allows for hygienic disposable of waste material without theoperator coming into contact with any residual waste material which mayhave been left on the edges of or about the aperture by previous users.It also provides less surfaces which may be subject to soiling by wastematerial when waste is deposited.

The handle 34 may be adapted to include a removable cover (not shown)for protection to impact or wear and tear during transport. The coverwould preferably be snap-on to eliminate the need for fasteners oradhesives that would need replacing. The handle 34 may also be a varietyof other shapes as will be appreciated by the skilled person.

Alternatively the handle 34 could be replaced by a hands-free design,such as a foot pedal, or sensor operated touch-free system that wouldallow the user to move the lid to the open position without needing tocontact the lid in any way. These options may be incorporated into theinvention in a manner that would be well understood by persons skilledin the art.

As would be apparent to the skilled person there may be a benefit inmaintaining a substantially airtight seal (not shown) between the lidside 31 and the body side 22. This substantial airtight seal, formed byinteraction between the lid side 31 and the body side 22, would allowmovement, but minimise the air flow, between the lid side 31 and bodyside 22. The substantially airtight seal may be formed by any suitableseal type such as frictional, or of a brushing or gasket type, as wouldbe appreciated by persons skilled in the art.

Both the body 20 and lid 30 may be multi-sided (e.g. square, pentagonal,etc.) as would be appreciated by a skilled person. However, as seen inthe Figures, it is preferable that the base 20 and lid 30 together forma substantially cylindrical shape having one continuous side in each,and the base 21 is substantially convex when viewed from the outside ofthe receptacle 1. When there is more than one side, i.e. the shape ofthe receptacle is triangular, square etc., the lid and body will havethe same number of sides and the lid will move telescopically within thebody, the walls of the lid being able to move in a reciprocal mannerpast the walls of the body.

The cylindrical shape of the lid 30 and body 20 and the convex shape ofthe base 21 is a preferred configuration because there are no corners orrecesses and it allows easy alignment when placing the receptacle withinthe support means. The telescopic nature of the relationship between thelid 30 and the body 20 also minimises the existence of corners orrecesses that occur with hinged lid systems and like options. Thisallows easier cleaning of the inside of the receptacle, and quicker morethorough and therefore more hygienic drying. With sanitary binsparticularly such hygiene issues are extremely important.

Preferably the body 20 is of a generally elongate shape. This allows amore ergonomic access to the receptacle 1 from either a standing orseated position. The length and cylindrical shape of the body 20 alsoallows for greater compaction of the waste material contents of thereceptacle 1 under its own weight. There are also a number of otheradvantages arising from the elongate shape, including a reducedvisibility of the bottom portion of the receptacle and its contents,better utilisation of space.

As would be appreciated, the length of the receptacle 1 could beadjusted as would be known by people skilled in the art, to accommodatevarying environments for the receptacle to be used in, differentapplications of the receptacle and variations in servicing of thereceptacle 1 including frequency of servicing. While preferred, theelongate shape is not essential.

The receptacle 1 as shown in FIGS. 1 and 2 the body 20 includes anexternal support flange 24. The flange 24 preferably extends from thesides 22 of the body 20, and is positioned adjacent to the open top 23.As best seen in FIG. 2, the flange 24 includes a concave shape to theunderside 26 of the flange 24. The flange 24 encircles the body 20 ofreceptacle 1. As will be appreciated the flange 24 need not becontinuous and need not completely encircle the receptacle 1.

The flange 24 is also adapted to interact with a support means 60 toallow secure stowage of the receptacle. One option for a support means60, a wall mounted support means, is shown in FIGS. 1 and 2. In thisoption, the support means 60 includes at least one wall mounted base 61attachable to a wall or other surface (not shown). A projection 62extends from wall-mounted base 61. A rail 63 (best seen in FIG. 2) isconnected to the projection 62 and is adapted to releasably support thereceptacle 1. The receptacle 1 fits inside the rail 63 and the rail 63abuts the concave side 26 of the external support flange 24 thus holdingreceptacle 1 in position. As an additional option, the flange 24 couldfurther be adapted to include a snap on protecting ring that could beused to reduce the effect of impacts or other damaging actions that canoccur on transport of the receptacle.

The receptacle 1 is easily removed from the support means 60 by liftingand can be simply swapped for a clean receptacle. The preferred elevatedmounting of the receptacle 1 on the wall also provides more ergonomicaccess for the user from either a standing or seated position. It alsocreates an uncluttered and pleasing usual effect of the receptaclefloating in space above the floor. The height of the supporting means 60on the wall or other appropriate surface can be positioned to suit theinstallation requirements of the receptacle 1.

The flange 24 also preferably includes a locking mechanism 27 (bestshown in FIG. 2) which interacts with the projection 62 to hold thereceptacle 1 securely in place on the support means 60. The lockingmechanism 27 may simply be a slot or groove in the flange 24 that fitsreleasably around the projection 62 thus preventing movement of thereceptacle 1 around the rail 63. A preferred embodiment of the lockingmechanism 27 is best seen in FIG. 5. The locking mechanism 27 could alsoinclude a device to prevent the receptacle from being lifted off thesupport means 60 if needed. Such devices would be known to a skilledperson.

While the flange 24 is represented in the Figures as being substantiallycircumferential, it is to be appreciated that the flange 24 need notextend around the full circumference and may include two or more spacedapart flanges, for example.

As seen in FIGS. 1 and 2, there may also be more than one support means60 used. The second support means 64 is adapted to hold the receptacle 1in place to prevent undue movement.

In FIG. 3 the receptacle 1 is shown with the lid 30 in the closedposition. In this position, the sides 31 (obscured in FIG. 3) of the lid30 are positioned below the open top 23 of the body 20. The aperture 35is therefore also below the open top 23 of body 20 and lies adjacent tothe sides 22 of the body. As a result aperture 35 is inaccessible andnot visible from the outside of the receptacle. This visual effect isimportant as it maintains the clean lines of the receptacle as a whole.In addition, as discussed earlier, the aperture 35 is within the body20, any waste material that may be visible about the aperture 20 is heldwithin the body 20. The receptacle is therefore more hygienic as wastematerial is within the receptacle body 20, rather than on the outside ofthe receptacle body 20 as would occur if the lid was positioned outsidethe body 20.

An alternative option for support means is also shown in FIG. 3. In thisoption, the support means 60 is a pedestal arrangement which includes ofa base 65 adapted to sit on the floor or other such surface. The basewill preferably be of any suitable heavy material to provide a lowcentre of gravity and thus provide stability. The base 65 may sit flaton the floor, or may include a plurality of feet (not shown). The feetwould be in a configuration and number to maximise the stability of thereceptacle 1.

An elongate extension 66 is engageable with the base 65 at one end andengageable with a projection 62 at the other. The projection is attachedto a rail 63 as described in FIGS. 1 and 2. The receptacle 1 fits insidethe rail 63 and the rail 63 abuts the concave side 26 of the externalsupport flange 24 thus holding receptacle 1 in position also asdescribed in FIGS. 1 and 2. As will be appreciated, the elongateextension 66 would be of a sufficient length to allow the length of thereceptacle to be supported above the base 65 when the flange issupported by the rail 63. The elongate extension 66 may also be ofsufficient height to leave space between the base 21 of the body 20, andthe top of the base 65 of the supporting means 60 to allow easy cleaningof the base 65 and the area around this.

The elongate extension 66 can be of any shape or size as required,including for aesthetic requirements, as would be appreciated by personsskilled in the art. In FIG. 3, the elongate extension 66 is shown as aconcave sheet which mirrors the shape of the body 20. The elongateextension 66 may preferably be of another configuration, for example around pole (see also FIG. 6) or a substantially rectangular shape.

FIG. 4 shows detail of the receptacle 1 with the lid 30 in the openposition. As can be seen, the body 20 may also include a protrusion 28which acts as a retention mechanism that prevents the lid 30 from beingcompletely removed from the body 20 when moved into the open position.

In a preferred embodiment of the invention, the protrusion 28 ispositioned at the upper portion of the body side 22. When the lid 30 isinitially fitted into body 20, the lid 30 is forced into position withinthe body 20 by pressure exerted in the direction of base 21 of the body20. This forces the lid side 31 to ride over the protrusion 28. Once thelid 30 is fitted into the body 20, the protrusion 28 sits within theaperture 35 as shown in FIG. 4. The bottom edge 38 of the aperture 35catches on the protrusion 28, preventing the lid 30 from being easilyremoved from the body 20. The sides of aperture 35 prevent excessrotational movement.

As an alternative, the lid wall 31 beneath the aperture 35 (shown at 39on FIG. 4) could include a channel (not shown) adapted to receive theprotrusion 28. The channel would increase the ease by which the lid 30could be inserted into body 20 over the protrusion 28. As would beapparent to the skilled person, the channel may include a barrier toprevent the lid 30 from simply sliding out of the body 20 via thechannel. Alternatively the lid 30 could simply be rotated within thebody 30 to take protrusion 28 out of line with the channel.

The rotation of the lid 30 also allows the position of the aperture 35to be placed at an angle accessible to the position of the user. This isan additional distinct advantage of the telescopic nature of thereceptacle lid 30. In addition to advantages from a minimisation ofcorners and crevices resulting in hygiene advantages, the ability torotate the lid thus allowing the user to adjust the position of theaperture 35 is a distinct advantage over the use of hinged or otherwisefixed lids. This allows greater utilisation of space while allowingergonomic access to the aperture 35 by the user from either a seated orstanding position. The rotation also ensures that the aperture 35 iseasily accessible to the user when the lid 30 is in the open position,allowing for easy access of the waste into the receptacle 1, while alsoensuring that sight into the receptacle 1 is minimised. As will bereadily apparent, the ability to rotate the lid 30 to at least a limitedextent will be restricted to those receptacles that are cylindrical orotherwise circular in shape such as shown in the preferred embodimentsof the Figures. This at least partial rotatability is why thecylindrical option is a very much preferred option. It may also be anoption however, to have top portion of the lid 30 rotatable while thelower sides of the lid are not. This may be an option in multisidedreceptacles but it is not preferred as, again, it will increase theamount of crevices in the device and will also add to cost. It is also apreferred option to have the lid 30 being rotatable only when in openposition.

Also as seen in FIG. 4, the lid 30 may include a circumferential lip 36(also indicated in FIG. 2) which extends from the lid 30 and ispositioned above the aperture 35. When the lid 30 is in a closedposition, the lip 36 abuts the body sides 22 to prevent the lid 30 frommoving too far into the body 20. The lip 36 is preferably shaped toreadily fit with the shape of flange 24. The lip 36 is positioned highenough so that the aperture 35 is inaccessible when the lid 30 is in theclosed position. This ensures that no waste material can escape, andthat the receptacle 1 is sealed when not in use to limit the extent ofodours being released. The optional presence of lip 36 can furtherincrease the hygienic advantages of the receptacle 1. As will beappreciated, the lip 36 need not be completely circumferential. Otheroptions to prevent lid 30 movement into the body 20 may also be used.

The lid 30 may also include on the inside surface, for example at 37 inFIG. 4, a hook or other such fastening means to allow the attachment offreshness products. For example antibacterial scented quills which wouldallow a fresh scent to escape when the lid 30 is moved into the openposition. Previously, such options were only able to be readily providedby placing freshness products in the base of the receptacle. This hadthe disadvantage that waste products would cover the freshness productslimiting and interfering with the scent over time. The present inventionallows the option of overcoming this distinct disadvantage.

FIG. 6 shows the receptacle 1 in a closed position held by analternative form of support means 50. The support means is in the formof a pedestal having a wide and preferably weighted base 51 togetherwith a stand 52. The stand 52 has a loop (obscured in FIG. 6), thatcould be a partial loop or a complete loop, which is adapted to fitunder the flange 24 and hold the receptacle 1 in place. The base 51includes a recess (obscured in FIG. 6) that is adapted to receive thedomed shaped bottom 53 (partially obscured in FIG. 6) of receptacle 1.This support means 50 is therefore a stable and secure support optionfor the receptacle 1 in its preferred form having a domed bottom. Suchsupport means also forming part of the invention to which theapplication is directed.

With reference to FIG. 5, the concave nature of the underside 26 of theflange 24 can assist in ease of carrying the bin. The flange 24 may alsobe adapted for use in storing the receptacles, or in stowing them fortransport (not shown). A series of racks may be provided, for example ina truck or in a stand alone unit, which may allow the receptacles to besuspended from the racks via the flange 24. The racks may besubstantially horizontal, and in contact with opposite sides of thereceptacle via the flange. Alternatively, individual support means maybe provided, which are adapted to receive the receptacles in a similarmanner to the support means described above. Other options for stowagemay be used as would be known in the art. The stowage options may takeadvantage of the locking mechanism 27 if required, for example in trucktransportation where the loads in the truck may be required to be keptsecure.

While the above description describes preferred support means,alternatives may also be used. For example, the supporting means may bea claw shaped support which extends from the wall in which thereceptacle may fit. As will be apparent the mounting surface to whichthe receptacle is attached is preferably a vertical wall. However theapparatus could be attached to surfaces having curved or other angularaspects if needed. The combination of receptacle plus means supportcapable of being a kit. Alternatively, the receptacle may fit into anopening in a bench top so that the flange 24 abuts the bench top surfacearound the opening, thereby holding the upper portion of the receptacle1 in an accessible position above the bench top. The lower portion ofthe receptacle 1 could be obscured below the bench top, for example bymeans of a cupboard or wall. Such alternative support means whichexploit flange 24 and/or the shape of the receptacle 1 would beappreciated by persons skilled in the art.

It would also be appreciated, that while less preferred, the base 21 ofthe receptacle 1 may be substantially flat, allowing the receptacle 1 tosit independently of a support means on the floor or other such surface.The domed shape of the base as shown in the Figures is however,preferred.

The receptacle 1 may also be made of any suitable material and bymanufacturing methods that would be well known in the art. When thereceptacle is made of plastics material, these manufacturing methodswould include blow or injection moulding techniques for example.
